The Google Play Store is overwhelming, with millions of apps and games to choose irefrom. We have purposefully not included Google apps in this list. Most users are already familiar with them. You can stuff tons of reading content onto these things and carry more literature in your pocket than even a library could dream of.
Remember, this approach has nothing to do with Android ADK! This example consists of two parts: An interrupt is generated when a new byte is received.
Here is a shortened excerpt: Simply put, this is a very simple software PWM. This happens when the Android side sends data to the Arduino.
The interrupt routine is extremely basic: Since we are doing no multi-buffering shenanigans the handling is extremely simple no need to call cli or anything. Download the complete example here: During USB initialization, the Arduino USB serial converter is set up and after that, communication is done using the bulk IN endpoint of the very same serial converter.
The source code is available here: Many parts of the code are probably familiar to Android SW engineers. The most interesting section is in the class UsbController where the Arduino device is set up and communication is initiated.
By notifying sSendLock of the UsbController the data will be transferred. Device filters — and therefore automatic activity launch when connecting the Arduino — are not used in this example in order to make the code simpler to comprehend. However, this could be easily implemented with a few lines of additional code.
It has also been successfully tested with an Android Tablet, the Acer Iconia Tab A, this tablet does not need any additional adapter cables. All code you find in this post can be used under GPL for your own projects.
Also, the future promises even more host availability on mobile phones. This opens up an entire range of new possibilities for already existing hardware as well as newly designed hardware for phones. However it lacked of a few crucial points.
On the one hand, this means that an already existing USB device mode gadget cannot work with your Android device. Therefore, if a manufacturer wanted to support Android phones it was necessary to create new hardware as well as new firmware.
Secondly, the new hardware had to be designed to power itself and also deliver power the Android device; this implied that mobile gadgets require their own power source. And secondly, there was another issue: Even then, it was up to the manufacturer to actually include the required stack in the OS.
But wait, there is another way to communicate over USB. As long as the kernel on the Android device supported the USB standard driver of the hardware mass storage, input, etc.
It most likely uses a USB-serial port and probably comes with a Linux or Windows driver as well as some software. Therefore, if you want to load your driver you will need to root your tablet, determine the version of your current kernel, find the kernel sources online, hope that everything compiles to have your driver ready and then load it onto your tablet.
In the end, when you finally have your kernel driver running, you will be required to write C code as well as some JNI glue to communicate with your Activity or Service in Android. All in all, this approach is not very straightforward.
Writing your own USB soft driver There is a very elegant solution to aforementioned problem. It requires far less skills in hacking and porting than the mentioned approach.
However, you will require some advanced knowledge in Android programming as well as some USB know-how. In the end, your result will be portable across all Android devices that have USB host enabled and have Android version 3.
Moreover, this solution does NOT require root access to the tablet or phone.Android (API level 19) introduces the Storage Access Framework (SAF). The SAF makes it simple for users to browse and open documents, images, and other files across all of their preferred document storage providers.
